Sample Tube, 5mL, External Threads, PP, White Graduations & Marking Area, Round Bottom

These 5mL sample tubes are designed for the reliable storage and transport of biological materials in laboratory and clinical environments. Manufactured from high-quality, non-toxic polypropylene (PP), the tubes offer excellent strength, durability, and clarity for easy sample identification.

The external thread design provides a smooth and uniform inner surface, helping to reduce the risk of contamination. Each tube features white graduations and a dedicated marking area for accurate measurement and easy labeling. The round bottom design supports efficient sample handling and processing.

Compatible screw caps are also made from polypropylene, ensuring the same coefficient of expansion as the tubes. This, combined with an inner sealing lip, delivers a secure, leakproof seal even under changing temperature conditions. The caps feature a long skirt and a quick-turn thread design, allowing for fast and easy sealing or removal. Optional silicone O-ring caps are available for enhanced sealing performance.

Ideal for research labs, diagnostic facilities, and sample collection applications, these sample storage tubes provide dependable performance and sample integrity.
